As shown in FIG. 3, the keyboard controller 33 is connected electrically to the wiring board 31 and the mode-determining unit 23 via the conducting circuit 312, and receives and interprets the key signal from the wiring board 31 and the mode identification signal from the mode-determining unit 23 of the top module 2 so as to output a scan code corresponding to the key signal, and an identification code corresponding to the mode identification signal to the computer device 6. The scan code is interpreted by the interpreting program 61 based on the identification code so as to generate a key code complying with the desired keyboard input mode.
FIGS. 4 to 6 illustrate the second preferred embodiment of a computer keyboard assembly according to this invention, which is a modification of the first preferred embodiment. In this embodiment, the mode-determining unit of the top module (2 a) includes a switch member (23 a) operable so as to generate the mode identification signal corresponding to the desired keyboard input mode. In this embodiment, the switch member (23 a) is a multi-bit switch, such as an 8-bit DIP switch, mounted on the bottom side 201 of the frame body 20, as shown in FIG. 5.
The top module (2 a) further has a connector 24, such as a plug, mounted on the bottom side 201 of the frame body 20 and connected electrically to the switch member (23 a) of the mode-determining unit.
The bottom module (3 a) further has a connector 34, such as a socket, disposed on the top wall (301 a) (see FIG. 4) and connected electrically to the keyboard controller 33 and the connector 24 such that the mode identification signal from the multi-bit switch (23 a) is transmitted to the keyboard controller 33 via the connectors 24, 34, as shown in FIG. 5.

The following are some of the advantages attributed to the computer keyboard assembly of the present invention:
1. Since the top module 2, (2 a, 2 b, 2 c, 2 d) can be separated from the bottom module 3, (3 a), mechanical malfunctions resulting from dust or stain can be obviated by simply cleaning the computer keyboard assembly. Furthermore, if the top module 2, (2 a, 2 b, 2 c, 2 d) is damaged, repair can be achieved by replacing the damaged top module 2, (2 a, 2 b, 2 c, 2 d) instead of the whole computer keyboard assembly, which is easier and cheaper.
2. In actual use, since the keyboard controller 33 generates the identification code based on the mode identification signal from the top module (2 a, 2 b, 2 c), the same bottom module (3 a) can match various top modules (2 a, 2 b, 2 c). Therefore, production of the computer keyboard assembly of the present invention can be simplified.
3. Since various operating devices, such as the joystick device 211, the rolling wheel device 212, the touch pad device 213, and the game control device 214, can be mounted on the top module (2 d), the computer keyboard assembly of the present invention facilitates different input operations.
While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
